I watched entire video in hope Matthew Moore would expand on his comment:
I wont even stop doing Linux videos. But participation in the various community is another issue. The jury is still out on that. Might just start my own. I have a free website now. It's not enough to host a chat room, forum and chat server. I would like that but i don't have the finances for it right now. ï»¿
from his video The Linux Community is a Hostile Environment
I find his videos very interesting and educational and look forward to seeing new ones.
For what it is worth, I would suggest, if possible, Mathew turn off the option for viewers to post comments or just ignore them and refer viewers to this (or his own forum if he starts one) like Spatry does where the posts and posters can be moderated.
